Poly(N-iso-Pr acrylamide) (PNIPAM) is a commonly investigated thermoresponsive polymer that exhibits a number of interesting phys. behaviors. Here, we use small-angle neutron scattering (SANS) measurements to determine the conformation of PNIPAM in two regions of the chain when it is grafted at moderate grafting densities to the surface of SiO2 nanoparticles (rNP ≈ 10 nm). At these grafting densities, polymer chains may adopt two primary conformations, depending on the specific value of the second virial coefficient, the mol. weight of the chains, and other properties. The nanoparticles are studied in D2O and ethanol-d6 to ascertain the effect of solvent quality on the chain conformation in both the inner and outer regions of the brush. The SANS measurements are interpreted using a modified Daoud-Cotton model that connects the Flory-Rehner theory of microgel thermodn. to the structure of polymer-grafted nanoparticles.
